A deep drag body for fine exploration of combustible ice

Abstract

The invention relates to a deep towing body used for fine exploration of combustible ice, and belongs to the field of marine resource exploration equipment. The deep towing body comprises a top plate,a chassis, a signal source, a towing body framework, a balancing tail, a towing connector, an electrical hub connection box and a loose-proof clasp. The top disk is located at the upper end of the skeleton; A chassis, the signal source is located at the lower end of the trailing body skeleton, the chassis and the bone trailing body frame are connected by the anti-loosening buckle in an embedded manner, and the signal source and the chassis are threadably connected; The balanced tail fin is installed on the tail part of the skeleton in a modular manner. The connection position of the towing connector and the towing body skeleton is adjustable; The electric hub connection box is arranged at the front end of the skeleton, and is connected with the skeleton through a clasp. The main investigation equipment is arranged along the centerline of the towed body navigation direction, optimal design of flow front, adding modular stern fins, on the one hand, the geometry and layout of facing surface enhances the automatic heading correction ability of deep towed body, on the other hand, it reduces the fluid resistance in the process of towed body moving upward and downward, so that the towedstability of towed body under the influence of ship turbulence is improved, and the quality of deep sea exploration is greatly improved.

Description

technical field [0001] The invention belongs to the field of marine resource exploration equipment, and in particular relates to a deep-sea towing body, in particular to a general-purpose deep towing body that can be used for fine exploration of combustible ice. Background technique [0002] Combustible ice is recognized as the most promising strategic reserve resource to replace oil. The deep-sea drag body can realize long-term and large-scale seabed exploration, and is one of the most effective exploration methods for combustible ice. At present, my country's combustible ice has gradually entered the period of detailed investigation and trial mining, and the accuracy of conventional exploration methods is not enough to meet the more urgent needs of fine exploration in mining areas. In order to improve the detection accuracy, western developed countries have developed hybrid deep tow and double deep tow seismic technologies, such as the French PASISAR system, SYSIF system, ...

Problems solved by technology

At present, my country's combustible ice has gradually entered the period of detailed investigation and trial mining, and the accuracy of conventional exploration methods is not enough to meet the urgent needs of fine exploration in mining areas.

In order to improve the detection accuracy, western developed countries have developed hybrid deep tow and double deep tow seismic technologies, such as the French PASISAR system, SYSIF system, and the American DTAGS system. Some breakthroughs have been made in the fine exploration technology of combustible ice at the seismic source, but there is no deep towing body that can be used to apply this kind of combustible ice exploration technology to the deep sea. It has gained valuable experience in the application of large-scale deep-sea technical equipment. At the same time, it has built a public research and development platform for deep-sea technical equipment relying on sound infrastructure and talent teams. It has the conditions for large-scale deep-sea technical equipment from research and development to various tests and finally to practical applications. Good conditions for the development, application and promotion of deep towing bodies for fine exploration of combustible ice
